Lincoln Advanced Technologies is the primary thought leader in respiratory based biosecurity


Inspired by the devastation of the September 11th terrorist attacks and anthrax letters, we realized that no existing respirators were capable of protecting the American public from bioterrorism.

Lincoln Advanced Technologies LLC is an early stage developer of personal protective equipment (PPE). Lincoln’s patented respirator, Respira™ is an extended wear bio-respirator mask specifically designed to be more effective during pandemic conditions than the currently used N-95 respirator, PAPR or military style gas mask (NBC). Respira™ is intended to protect the “critical infrastructure” segments of a country’s economy during an epidemic, comprised of health, defense, security, energy, finance, transportation, utilities and government at national, state and local levels.
